Panchang in Sevan, Gegharkunik, Armenia Sun 9 Mar 2036

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 21:44 on Sun 9 Mar to 18:47 on Mon 10 Mar, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Sun 9 Mar. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 07:20 here. Ekadashi ended at 00:38, before it. Dwadashi ends at 21:44, when the lead reaches 144°. The lead passed 0° at the new moon of 27 Feb, so the Moon is waxing: Shukla paksha.

The night of Sat 8 Mar ran from sunset 18:59 Sat to sunrise 07:20, 12 h 21 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:20 to 19:00, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:00 to 07:19 Mon, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Pushya spans 93°20′–106°40′; the Moon entered its pada 3 at 100°. It leaves at 17:19, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 324.8° + 100.6° = 425.4°, one full turn and 65.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 09:21, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava runs until 11:12, when the lead reaches 138°; Balava until 21:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:20 to 07:19 Mon, so the hours after midnight still belong to Raviwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 28 Mar, finds it in Meena and begins Chaitra.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 27 Feb, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 2035, 14:57 Sun. Since then the Sun has moved 330.7° round the stars. Vikram Samvat numbers that year 2092; Shaka Samvat numbers it 1957.
